[PATCHv4 1/4] OMAP3: Devkit8000: Change lcd power pin

[Thomas Weber]

This patch fixes a wrongly used lcd enable pin.

The Devkit8000 uses twl4030_ledA configured as output gpio only for the
lcd enable line. twl4030_gpio.1 is used through the generic gpio functions
while ledA is used via low level twl4030 calls.

Remove the low level calls and use the generic gpio functions for
initialization and use of ledA.

This also fixes a bug where the lcd would not power down when blanking.

Fix indentation issue. The comment line uses 8 whitespace.
This is replaced with one tabulator.
